Normal proportioned and small are bantams. Dwarfism is very rare, and FTT is more common. I wouldn't be surprised if it was. I'm sorryWelcome to BYC!
Might be a FTT (failure to thrive) chick. Chicks that live usually grow up to be normal sized chickens, but I have seen a few cases where the birds stay small their whole lives. Dwarfism is a thing in chickens, but those birds are usually small with short legs, instead of being normal proportionated and small.
